Weather Fronts

Cold Front- fast moving cold air meets slowly moving warm air and because cold air is denser it stays low to the ground and the warm air rises over it. As the warm air rises, it cools to the temperature that water vapor in the air condenses. Strong winds and thunderstorms are often linked with cold fronts and if there is enough moisture in the air, there could be heavy rain.

Warm Front- warm front happens when slowly moving warm air meets slowly moving cold air. The warm air rises over the cold air because it is less dense. Warm fronts are often accompanied by clouds, storms, and rain. Because the front moves slowly, the weather may be rainy or foggy for several days.

Stationary Front- a stationary front happens when cold air and warm air meets, but neither had enough force to move the other one. When the cold air and warm air meet the water vapor in the warm air condenses into rain, snow, fog, or clouds. The stationary front can remain over an area for many days.

Occluded Front- a occluded front occurs when warm air is caught between two cold air masses. The denser cold air pushes the warm air up and cuts it off from the ground. The weather may become rainy or snowy because the air by the ground becomes colder.
